1998 Infiniti q45 common problems

The most-reported problem areas across all 14 owner complaints filed with NHTSA — and what to check before you buy.

Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Engine And Engine Cooling
Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
